Pakistan has performed poorly against India in multi-nation tournaments such as World Cup, Champions Trophy and Asia Cup. So I don't expect to Pakistan to win today. They are a very good team, but against India they seems to be having issues.
Pakistan after winning the toss selected to bat and are playing at 226/6 in 48 overs. Around 240 would be approx score which India would have to chase. So Pak would require couple of quick wickets in start to create any sort of trouble for the India.
